Contains accessibility and keyboard navigation specification of Telerik and Kendo web components.

Out of the box, the Kendo UI for Angular Segmented Control provides extensive accessibility support and enables users with disabilities to acquire complete control over its features.


The Segmented Control is compliant with the [Web Content Accessibility Guidelines (WCAG) 2.2 AA](https://www.w3.org/TR/WCAG22/) standards and [Section 508](https://www.section508.gov/) requirements, follows the [Web Accessibility Initiative - Accessible Rich Internet Applications (WAI-ARIA)](https://www.w3.org/WAI/ARIA/apg/) best practices for implementing the [keyboard navigation](#keyboard-navigation) for its `component` role, provides options for managing its focus and is tested against the most popular screen readers.

## WAI-ARIA


This section lists the selectors, attributes, and behavior patterns supported by the component and its composite elements, if any.

### Segmented Control Component


The Segmented Control is a selection component that allows users to choose between mutually exclusive options. It functions as a group of toggle buttons, with a visual indicator (thumb) that slides to highlight the selected option.

| Selector | Attribute | Usage |
| -------- | --------- | ----- |
| `.k-segmented-control` | `role=group` | Sets the proper role for the group of buttons. |

### Segmented Control Buttons


Each button within the segmented control represents a selectable option.

| Selector | Attribute | Usage |
| -------- | --------- | ----- |
| `.k-segmented-control-button` | `role=button` or `nodeName=button` | Each button must have the appropriate button role. |
|  | `aria-label` | Each button should be properly labelled. Use `aria-label` if the button contains only an icon without text. |
| `.k-segmented-control-button.k-selected` | `aria-pressed=true` | Only the selected button within the group will have this attribute set to true. |
| `.k-segmented-control-button.k-disabled` | `aria-disabled=true` | Indicates that the button is disabled and cannot be interacted with. |

### Visual Selection Indicator (Thumb)


The thumb is a visual element that slides to indicate the selected button. It should be hidden from assistive technologies.

| Selector | Attribute | Usage |
| -------- | --------- | ----- |
| `.k-segmented-control-thumb` | `aria-hidden=true` | The thumb is purely decorative and should be hidden from screen readers. |
